Have done it many times with just A&B at EC`s of 3.0 to 4.0 in times gone by, doing it twice a day at lights on and just before lights out, have also done it 3 times per day as well at mid day too whilst lights are on. To be honest i don`t worry about odd scorch mark on odd leaf and that`s all it is odd leaf, but if it happens it happens, tis no biggi. I use a few drops of washing up liquid as a wetting agent (a great bug repellent as well by the way) per liter and it`s only ever done in veg if i do it. Idea behind the high ec is its not avbailable constantly and only for a short time unlike feeding through roots ferts are ready as and when plant want`s, never had any problems running high EC and foliar feeding it to plants, in fact in doing so it corrects problems very much quicker than foliar feeding a lesser EC. Ive not done it for time tbh but i used to it regular and not always for treating defiencies. :)
Thanks for the feedback jimmi2scoops! That's interesting to hear that you spray mid day with your lights on :) Love the boisterous approach.
I can explain the reason why I go in low on the EC. You can tip the balance pretty quickly. When making any changes, I prefer the small, incremental approach. If I feel I need to add a lot of food, I increase the frequency of applications. I'd hate for someone to read this, go spray their plants with a high EC and burn them. If you know what you're doing and know the plants, of course you can go higher.
That`s just the thing though Grumpy they don`t burn and ive done it lots in times gone by, i don`t do it so much now but whjen i was keeping plants in smaller pots for moms then yes i did use this technique lots. Ive pushed as high as 4.0ec with no problems in past feeding twice daily to fix deficiencies and im not implying go in with mad high EC`s to start if people are clueless and don`t know what your looking at if shit starts going south fast, but for sure 2.0-2.5 ec of AnB won`t burn a nice sized vegging plant at all if it`s got deficencies, only thing you may notice as with any foliar spraying is odd scorch from light magnifying wet leafage, but that`s hardly a worry and its not like it`s everywhere it`s the odd leaf where as if they were cooking from overferting it would be every leaf, even newly rooted cuts that look rough that may have taken a little longer to root through i can foliar EC`s of around 2.0 under my t-5, in fact foliar feeding cuts that are taking a while to root through that are starting to look rough you can bring them back foliar feeding x2 daily, maybe not crazy high EC`s but yes i`d risk near as dam it 2.0 no worries myself, well knowing me i`d go in with 2.0 but airing omn bside of caution for growers here. As for 3 times daily well maybe that was a bit of experimentation cus x 2 daily is usually enough as lights come on and just before lights out. I never spray a flowering plant either unless it has a problem like bugs but tbh i dont get bug problems (touch wood)
Yes i`m with you too i wouldn`t wan`t anyone to go overboard with their plants especially if they don`t know what they are looking at and carry on spraying crazy high EC cus shit could go tits up fast, but as said x2 daily with a 2.0ec to cure a deficiency im confident in saying things won`t go tits up mate. Next time or if you get a problem that calls for a foliar feed to sort it, give it a go and maybe try 2.0 ec on a newly rooted cutting too that`s looking a bit rough for a few days. Basically using higher ec just cures deficiencies quicker than using a lower EC so it might only take 3 days before a plant looks lush green again or your seeing a nice positive result and plant greening up, then you can easily just just hold off foliar feeding to see how plant reacts over next few days if your worried, problem is yes lots of growers aren`t as clued up as others so yes what im saying here is i here you mate.
Oh yes i`m not talking about organic ferts from a bottle here either guys i use mineral/chemical ferts.
